Glaucoma drainage devices are an option in refractory glaucomas for control of intraocular pressure (IOP). We evaluated the outcome of pars plana Ahmed glaucoma valve along with triamcinolone-assisted vitrectomy in 11 eyes with uncontrolled IOP on maximum tolerable antiglaucoma therapy. The mean preoperative IOP of 33.64 +/- 5.99 (range 26 to 44 mmHg) decreased to 17.09 +/- 2.26 (range 14 to 20 mmHg) and 17.45 +/- 1.81 mm of Hg (range 14 to 24 mmHg) at 6 and 12 months following surgery. The mean number of antiglaucoma medications decreased from 3.27 +/- 0.05 to 0.64 +/- 0.67 and 0.55 +/- 0.6 at 6 and 12 months following surgery.
